The short term liquidity offers were similar to those in past weeks and mature on Monday.

The central banks have been offering cash to financial institutions on almost a daily basis for the last weeks as the financial sector has become wary of lending to anyone — including other banks — and credit has become more scarce as a result. Interbank lending rates remain abnormally high, and stocks have fallen on fears that the supply of credit to businesses is being choked off, threatening a recession.

The ECB said it got 62 bids for $93.88 billion on its offer. The marginal interest rate on the money was 0.5 percent.

The SNB said it got 17 bids totaling $11.9 billion on its offer. The weighted average interest rate on the money was 2.4 percent.

The BoE had its regular stipulation of 10 bids on its offer, which asked for $8.48 billion. The weighted average accepted rate on the BoE's money was 2.009 percent.

A statement on the BoE's Web site said "The overnight U.S. dollar repo operations will continue for an amount of $10 billion until further notice.

"In addition, the Bank will each week conduct two U.S. dollar repo operations for one-week maturity, one each Tuesday and the second on each Friday. These will each continue at their present level of $30 billion until further notice.

"The Bank's Standing Facilities have been, and continue to be, available everyday throughout the day to all participating banks, against eligible collateral and at a penalty rate of interest. Together with other features of the framework, these facilities were designed to help the system cope with stressed market conditions."
